Grips
 

What are the best grips for a XC mtb?

I prefer ODI rogue clamp on grips.

What's the best flavor of ice cream?

Lock-ons are more convenient. I have Lizard Skins Northshore grips on one of my bikes and like them.

I have ESI Chunky grips on two of my bikes. Those are not lock-ons. I find them a bit more comfortable, but they're more of a hassle to get on and off unless you have an air compressor. They also get slippery without gloves when they're wet, so I have to wear gloves with those because of sweat(but I always wear gloves when mountain biking anyway, so that's not a problem for me.)

I use Ritchey WCS Truegrip foam grips. I will may try ESI chunky next, but I like the Ritchey grips.

Not the Jenson house brand. In 8 hours of riding parts of the knurl started rubbing smooth.

ESI. Love the grip and comfort factor they give me. I feel dialed in with them.

Raptor Scale are my favorites. I love mushroom grips but most of them are too thin, but these scooterheads made some that are thick enough. Sometimes I wish they were a tad longer.
